This inventionrelates to improvemcntsin cultivating instruments, andmore. particu larly to such asvare susceptible of use from the time ofplanting to maturity.

An objectin view ist-he productionof a ligl'i'Q-durable constructionadapted for use singly or in multiple, and so designed as to utilize avariable number of plates or shovels. i 1

A "further object the tlexibleretentiol'l ot' the plate fran'ie atvarious angles to the line of draft. i a 1 7 \Vith these and furtherobjects in view as will in part hereinafter become ap iiarent and inpart be stated, the invention comprises certain novel constructions,combina tions and arrangements of parts as subsequently specified and.clain'ied.

In the accompanying dra\vings,----

Figured a view in side elevation of a plow or cultivator embodying; thefeatures of the present invention.

Figure 2 is an end view tl'iercof.

Figure 3 is a planview thereof.

Figure 4: is a side elevation of the inside of oneof the frameplatesdetached and seen on an enlarged scale, the clamping bolts be lugseen in transverse section and the pivot pin in side elevation.

1 Figure?) is a verticalsection through the complete frame, parts beingbroken away, and the section being taken on a plane equal tothatindicatedby line of Figure 4.

Referringto the drawings by numerals, 1 indicates a draft beam formed ofa strap, preferably of steel or other appropriate material, bent andfolded back upon itself so as to produce acurved or parti-circularportion 2 at the-rear-from which extend forwardlynthetwo converging armsor laps of the strap, receiving between their forward portionsthablock 3to which the clevisreceiving loop 41 is attached; Obviously, any type ofdraft connection desired may be caused toengage loop 4.. Block 3 isbolted, riveted or otherwise appropriately and effectively anchored tothe draft beam 1, between the arms thereof..

Within the curved portion 2 of beam 1 is arranged a plate 5, which iswelded or otherwise appropriately anchored to the beam 1..

Extending upwardly through plate 5 is a pivot pin 6 having an aperturejust above the plane of the upper face of the plate, through whichaperture extends a locking key 7. The lower end of pin 6 is formed intoI 1,629,109 PATENT? .jorFi-cs, a:

a hall 8.2 Arranged transversely of andpjust beneath draft beam lis a pate frame made up of bars19, 9, secured together by clamp; ing bolts 10,10. 1 Each bar 9 isformed with a parti-globular recess 11 registering'with each other and jointly forming, a socket for ball'S. Each of thebars 9 is formed wit-ha groove leading-j upwardly from the respec? ti'verecess 11 for accommodating the bodyiof pin 6, so that, while the pin'iseffectively anchored between bars 9, theframe made up of said bars isfreeto swing angu-larlyabout the pin and thus assume various angularreslations to the line of draft. Theparts are preferably"proportioned tocause the upper edge of the plate frame, thatris the frame made up ofbars 9, to rest against theunder faccof plate 5. o v J a.

A groove 12, similar to that extending upwardlv from rec'essll in eachplate 9, ex-

tends dmvnwardlytherefrom to receive a standard of a plate or cultivatorshovel.

Similar grooves 13, 13,, similarly registering are formed at variousplaces in, the length of bars 9.v Grooves 13, however, preferz'iblyextend entirely across'the full width of the respective bar, there beingpreferlably 'a number of equally spaced grooves 13 .for providingan oddnumbervof shovel standards when grooves 12' are counted, the

. grooves 13 nearest to grooves 12 being spaced the same distancefromgrooves 12 as'the nearest grooves 13 are spaced from each other,whereby, whenall of grooves 13 and 12 are employed, there will bean oddnumber of shovel standards spaced equally throughout the length of theplate frame;

Five such standards have been provided for in the odd number shown inthe drawings, but, obviously, the number ma v-be,va-. ried as desired.However, whenfi'romfthe' spacingv of rows, or angularity at frame, orother cause, it becomes desirable to employ an even number of shovelstandards, the grooves 12 are not utilizecL-andthe grooves 18 nearergrooves 12 ateach side (113831805 not employed, but instead' there areprovided extra grooves 14. 14, spaced apart thesa'me distance that eachis spaced from the nearer end grooves 13, whereby, by the use only ofthe end grooves 13 and the grooves 14, an equal number of shovelstandards may be used and spaced equally.

One of plates 9, preferably the rear one, is provided with a set screw15 for each pair of grooves 12, 13 and 14, and the standardswardends-anchored, preferably adjustably,

to the draft beam 1, that the shovel frame may swing on the pivot pin 6whenever a 1'7 strikes an obstaclerequiring flexing of the parts. ;Theanchorage of each spring 19 to beam 1 is susceptible otwvide variationwithin the spirit and intent of this invention, and one preferred termis shown aseonsisii ng of a block 20 having an eye 21 engaging therespective spring. A bolt'22 engages each block 20 and extends throughany of apertures 23', 23 tor-med in beam 1. When theshovell frame is toextend normally at right angles'to the line of draft, as seen in thedrawings, the bolts 22 extend through transversely ahned apertures 23,as shown. but, if it becomes desirable to var v the angle of the shovelframe to the line of d ra lt', one of the bolts 22 is placed in one ofthe tow ward apertures 23,- while the ot'l ier boltQQ is Vhat is claimedis 1-- 1.

*2. In cultivating apparatus, the combination of a. strap bent to-torm acurved portion and return arms providing a draft beam, a plate anchoredin and contorn'iing to the contour of the curved portion, and a shovelframe pivoted to the plate.

13. In cultivating apparatus, the combination of a draft beam, a pair ofbars forming ashovel frame, and a: pivot pin extending from the beambetween the bars for connecting the frame pivotally to the beam, the

bars being formed with registering grooves for receiving shovelstandards, one pair of said grooves being in line with the pin.

In cultivating apparatus, the combination of a draft beam, a pairof bars forming a shovel frame, and a pivot pin extending from the beambetween the bars for connecting the frame pivo'tally to the beam, thebars being formed with registering grooves for receiving shovelstandards, one pair of said groovesbeing inlinevvith the pin. the beingsin'iilarly grooved to aceouunod-atethe pin and the grooves for the pinterminating in parti-globular recesses, and the pin being formed with aball fitted within said recesses.

In cultivating apparatus, the combination of a draft beam. :1 pair ofbars forming shovel frame, and a pivot )in extending from the beambetween the laars for cornuect-ing the frame pivotally to the beam, thebars being formed with registering grooves tor receiving shovelstandards, one pair oi said grooves being in line with thepin, thesewral pairs of grooves being equally spaced apart, and the bars beingtormed with other similar grooves equally spaced with respect tot'llOInsOlVQS and some of the first-mentioned grooves and unequallyspaced from the other of the first-mentioned grooves.

In cultivating apparatus, the combination of a bent strap havingreturn arms torining a dratt bean-1, the strap having a curved portionat the bend, a plate fit-ted and anchored in said bent portion, a.cultivator frame arranged trai'isve-rsely ot' the bean'i, a pin pivotedin :the tran'ie and extending through the plate, and a locking pinextending through the pivot pin at the opposite side of the plate from:tillfi tame.
